The pattern of the collagen fiber bundles of the capsule of the glenohumeral joint

摘要: The macroscopic anatomy and the architecture of collagen fiber bundles were studied in joint capsules 43 cadaver shoulders. All specimens transilluminoted by polarized light after preparation Spalteholz' technique. Areas high-fiber density complex structure examined histologically. macroscopically recognizable ligaments are composed several layers differing thickness orientation. A simple pattern radial circular fibers is found only relatively thin posterior capsule. cross-linking was visible superior capsule, a system spirally crossing each other present anterior/inferior examination under revealed continuous transition between ligamentous reinforcements at anterior inferior which radiated obliquely from glenoid rim varied greatly form complicated capsule would suggest that capsular cylinder has to be regarded as functional entity current biomechanical concepts must modified if we want understand its stabilizing effect. structural features new insight about pathogenesis rotator cuff tearing, can develop result shearing stress tendinous layers.
